HS Code 3102.80 – Fertilizers, mineral or chemical; nitrogenous, mixtures of urea and ammonium nitrate in aqueous or ammoniacal solution
HS code 3102.80 is the 6-digit subheading for fertilizers, mineral or chemical, nitrogenous, mixtures of urea and ammonium nitrate in aqueous or ammoniacal solution. It is used for urea ammonium nitrate (UAN) solution, UAN 28%, UAN 32%, liquid nitrogen fertilizer and aqueous urea-ammonium nitrate mixtures.
What HS 3102.80 covers
HS code 310280 pertains to nitrogenous mineral or chemical fertilizers that are mixtures of urea and ammonium nitrate in aqueous or ammoniacal solution. This category primarily encompasses Urea Ammonium Nitrate (UAN) solutions, which are highly popular liquid fertilizers due to their ease of application, uniform nutrient distribution, and ability to provide both quick-release (nitrate) and slow-release (urea) nitrogen. These solutions are widely traded internationally, with large agricultural chemical companies and cooperatives being key exporters. Importing countries are typically those with extensive arable land and mechanized farming operations, such as the United States, Canada, Brazil, and various European nations. Trade involves specialized storage and transport infrastructure (e.g., tanks, pipelines), quality control for concentration levels, and adherence to environmental regulations regarding handling and application, especially considering the CBAM implications for their production.

Codes often confused with 3102.80
Common mistake. This code can be confused with solid urea (310210) or solid ammonium nitrate (310230) if the 'aqueous or ammoniacal solution' form is not recognized, or with other liquid nitrogen fertilizers if the specific urea-ammonium nitrate mixture is not identified.
Top exporters and importers of HS code 310280, 2025
In 2025, the largest exporter of HS code 310280 in UN Comtrade data was Russia, with about 28% of world exports; the largest importer in UN Comtrade data was the United States, with 31% of world imports.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
